6 Introduction The BARIX X8 is an I/O to RS-485 Modbus converter for commercial interfacing, control and home automation applications. Using the industry standard Modbus protocol over 2-wire RS-485 the device can be controlled from any Modbus capable master. Eight independent configurable inputs/outputs allow the use of the BARIX X8 in a wide range of I/O applications: - General I/O to RS-485 converter (inputs and outputs) - Up to 8 push buttons (inputs) or LED s for status display - Local analog voltage reading (0-5VDC, 8 inputs) - Local temperature (up to 8 Barix TS digital sensors) - WIEGAND reader to RS-485 converter (2 inputs for D0 and D1, other 6 I/Os usable with standard functions) The device is configured via the serial interface using standard Modbus read/writes. If the device ID is unknown, a special command is available, which can be sent via broadcast and uses the serial number of the device to send it new configuration info. If the address of the device is not known, it can be reset to default parameters (see chapter Configuration ). The supported protocol is Modbus/RTU at (default) and 9600 Baud, with even (default) or no parity. BARIX AG 1/24

7 Hardware Case The BARIX X8 I/O to RS-485 Modbus converter comes in an open plastic case. Two mounting brackets with 5mm holes allow mounting on surfaces but can be cut off (predetermined cut line) if not used. Connectors The Power/RS-485, I/O (I/O, 5Vout,GND) and cable shield are available on 3 spring contact connector blocks for wires AWG28 - AWG16 / mm2 Power supply requirements The BARIX X8 is equipped with an universal power input and accepts both AC and DC voltage. The AC supply range is 12 to 24 Volts and 9 to 30 Volts when powered by a DC power supply. A voltage regulator controls the internally needed operating voltage of 5VDC. The BARIX X8 consumes with all outputs activated 1 Watt max. The BARIX X8 is reverse polarity protected. Attention: When powering the BARIX X8 and other BARIX devices (Barionet, IO12, R6), connected over RS-485, using a single power supply only a DC type power supply can be used as the RS-485 interfaces are not completely potential free. Inputs All I/O pins are directly connected to the CPU and the absolute rating is TTL level (0 to 5VDC). When used as digital input the signal is filtered (48 milliseconds period for debouncing) to allow for direct connection of buttons or contact closures. The analog value of each input is digitalized every 16 milliseconds (sampling rate 62.5 Hz) with a resolution of 10bit (0 to 1023) and is stored in separate Modbus registers. On each input a BARIX TS digital temperature sensor can be attached for precise temperature reading. Outputs All I/O pins are connected to the CPU directly and the absolute rating is TTL level (0..5VDC). Each output can sink BARIX AG 2/24

8 5VDC output RS-485 or source up to 20mA. See 5VDC output for total current limitations! A regulated 5VDC output is available to provide power to small devices, LEDs etc. To prevent overheating of the voltage regulator the sourcing current of 5VDC and all used outputs combined should not exceed 30VDC Vin, 24VDC Vin, 12VDC Vin or 100mA@ Vin <= 11VDC. The BARIX X8 has an RS-485 host interface, available on a spring contact connector block. Besides A and B signals for the differential, bidirectional bus signal, a third connection is available, commonly referred to as reference ground. This signal is internally tied to signal ground via a 100 Ohm series resistor. Termination resistors are NOT provided on-board. A termination resistor may be added at each end of the RS- 485 bus if required. The BARIX X8, as well as other Barix I/O extension units, feature soft pull-up (B) and pull down (A) 10kOhm resistors, which force the inactive bus to a relatively high impedance, idle condition. Both A and B line signals are heavily protected against ESD (Electrostatic Discharge). Supported interface configurations are baud, 8bit, even parity, 1 stop bit (**default**) baud, 8bit, no parity, 1 stop bit 9600 baud, 8bit, even parity, 1 stop bit 9600 baud, 8bit, no parity, 1 stop bit LED Indicators 4 LED indicators on the unit show the conditions CPU heartbeat as well as RS-485 receive and transmit activity. Configuration Memory The BARIX X8 contains 256 bytes of non volatile configuration memory (EEPROM) which can be read and (most of it) written via standard Modbus commands. BARIX AG 3/24

12 Protocol support General The BARIX X8 communicates via the Modbus/RTU protocol over its RS-485 interface. The unit is also configured via writes to Modbus registers. In addition to the actual I/O registers, a 256 byte information area is accessible which contains device type, software version, serial number, the configuration as well as user changeable storage. Attention: Writing to registers can take up to 10 milliseconds per address before being confirmed (Modbus acknowledge). Supported Standard Commands The following standard Modbus commands are supported by the BARIX X8. All other commands will be answered with an exception code. Due to the limited memory resources of the BARIX X8, the unit cannot receive messages larger than 95bytes and will ignore these (eg. write multiple register commands). CMD (hex) Function 03 (0x03) read (holding) register 04 (0x04) read input register 05 (0x05) write single coil 06 (0x06) write single register 16 (0x10) write multiple registers Special Commands The BARIX X8 supports some special, Barix proprietary, commands which have been implemented to ease configuration and facilitate the use of the BARIX X8 in conjunction with non-modbus systems. These commands are: CMD (hex) Function 68 (0x44) set all outputs on multiple units 69 (0x45) set configuration using serial number 70 (0x46) set coil without acknowledge 71 (0x47) erase firmware, enter download mode with setting 19200,n,8,1 Exceptions The BARIX X8 responds to malformed commands or access violations with the defined Modbus exceptions. BARIX AG 7/24

13 Command 68 The command code 68 (hex 44) can be used to set the outputs of a whole group of BARIX devices very fast and efficiently. The command is sent via broadcast and can address multiple units, with one byte per device carrying the information for all 8 outputs. All devices addressed by this command will synchronously set their outputs after the command is completely received. The devices will not send a response to this command. Command format: Byte 1-0x0 (broadcast address) Byte 2-0x44 (command code) Byte 3 - ah (first address, hi, always 0) Byte 4 - al (first address, Modbus address of first unit) Byte 5 - ch (count, # bytes, hi, always 0) Byte 6 - cl (count, #bytes, lo 8 bit) Byte 7 - nb (number of bytes following (redundant) Byte nb: data bytes for multiple devices Byte 8+nb+1: crc1 (crc1 according to Modbus spec) Byte 8+nb+2: crc1 (crc1 according to Modbus spec) Example: a command with al=5, cl=nb=4, data 01,02,04,08 will set the outputs on the BARIX X8 with Modbus address 5 to 01 which means output one on, all others off, outputs on the BARIX X8 with the Modbus address 6 to 02 which means output two on, all others off, devices with address 7 and 8 accordingly. All other devices with Modbus addresses 1..4 and are not affected by the command. Command 69 The command code 69 (hex 45) is used to set a BARIX X8 device which is connected to the bus and whose address is unknown (but serial parameters are correct). The command can also be sent multiple times with different serial parameters to find the device. The serial number of the device, which can be found on a label on the unit (format xxx-yyy), needs to be inserted into this block to address a specific unit. The block is sent out as a Modbus broadcast. BARIX AG 8/24

14 Bytes 272, 273, 274, 275 of the Modbus register map (configuration memory positions ) will be written with the provided information if the serial number matches. Command format: Byte 1-0x0 (broadcast address) Byte 2-0x45 (command code) Byte 3 - s1 (serial number, first part) Byte 4 - s2 (serial number, second part) Byte 5 - s1 (serial number, first part, repeated) Byte 6 - s2 (serial number, second part, repeated) Byte 7 - c1 (configuration data for register 272) Byte 8 - c2 (configuration data for register 273) Byte 9 - c3 (configuration data for register 274) Byte 10 - c4 (configuration data for register 275) Byte 11 - crc1 (crc1 according to Modbus spec) Byte 12 - crc2 (crc2 according to Modbus spec) Despite the broadcast addressing, the unit will respond with an acknowledge (containing bytes 1..6 plus crc)! Command 70 The command code 70 (hex 46) is used to set an BARIX X8 output without a return acknowledgment. The command uses the exact syntax of the 05 (set coil) command, but the BARIX X8 does not send an answer and is immediately ready to receive the next message. The command should be sent addressed to the device address and NOT as a broadcast, otherwise all BARIX X8 units on the bus will react to it. This command has been added to the BARIX X8 to allow slow systems, which are not Modbus native and cannot react fast to serial input (like common home automation systems) to set a series of outputs of one or multiple BARIX X8 units without the need to observe Modbus message timeouts, answers etc. BARIX AG 9/24

15 Command 71 The command code 71 (hex 47) is used to erase the firmware of a BARIX X8 device which is connected to the bus and whose address is unknown (but serial parameters are correct). The command can also be sent multiple times with different serial parameters to find the device. The serial number of the device, which can be found on a label on the unit (format xxx-yyy), needs to be inserted into this block to address a specific unit. The block is sent out as a Modbus broadcast. After erasing the firmware the device will go into the download mode with serial settings 19200,n,8,1. Command format: Byte 1-0x0 (broadcast address) Byte 2-0x47 (command code) Byte 3 - s1 (serial number, first part) Byte 4 - s2 (serial number, second part) Byte 5 - s1 (serial number, first part, repeated) Byte 6 - s2 (serial number, second part, repeated) Byte 7 - crc1 (crc1 according to Modbus spec) Byte 8 - crc2 (crc2 according to Modbus spec) Despite the broadcast addressing, the unit will respond with an acknowledge (containing bytes 1..6 plus crc)! BARIX AG 10/24

16 Configuration Default Parameters The BARIX X8 is configured via the RS-485 interface using standard Modbus commands. If the address of the device is not known, it can be reset to default parameters by the following method: disconnect the device from power supply install a wire between pin 8 and pin 9 on J1 reapply power to the device LED The BARIX X8 will lite up all 4 LEDs and the 3 rd LED will blink showing that the default parameters are stored in the non volatile memory. No communication is possible at this moment. disconnect the device from power supply remove the wire between pin 8 and pin 9 on J1 reapply power to the device Now the device can be addressed on Modbus address 255 using the following serial settings: Baud, even parity, 1 stop bit. BARIX AG 11/24

17 Connecting I/O Contacts on inputs The BARIX X8 features 8 I/Os which are set to work as inputs by default (Reg. 276=00h). The internal pull up resistors are enabled by default (Reg. 273=FFh). Buttons or contact closures can be attached to each input and to signal ground as shown in the schematic below. I7 I0 LEDs on outputs The 8 I/Os of the BARIX X8 can be set to work as outputs (Reg. 276=FFh). LEDs can be attached between each output and the 5VDC source as shown in the schematic below. R7 R0 LED7 LED0 BARIX AG 12/24

18 TTL devices on I/O Each BARIX X8 I/O can be set to work either as input or output. External device TTL level I/Os can be attached to the I/Os and to signal ground as shown in the schematic below. TTL level output TTL level input GND O4 I0 WIEGAND device One WIEGAND device (keypad, reader) can be interfaced by connecting output D0 to I/O6 and output D1 to I/O7 which are both inputs by default. +Vsupply WIEGAND D0 DEVICE D1 GND Vsupply The WIEGAND interface is enabled by setting Bit 6 of register 274 (Reg. 274 OR 40h). BARIX AG 13/24

19 To check if WIEGAND data is available the register 11 has to be read. The lower Byte will contain the amount of Bits received. If it is 00h then no new data was received. The higher Byte contains a bitmap of found temperature sensors (see next page) The Bits of the received WIEGAND data are shifted in (from right to left) into the Registers 12 to 16 (5x16=80 bits max): Regist er Bit Example: Register 11: 2B1A Register 12: A8DF Register 13: D8CA 1Ah=26 Bits Register 12 (Word) Register 13 (Word) A8 (High Byte) DF (Low Byte) D8 (High Byte) 02 (Low Byte) n n n n n n a a a a a a 5 6 Note: As the Bits are shifted in from right to left, the Bits in the last Byte are right aligned. The unused Bits can contain old data! To obtain correct data the last Byte must be masked. In the above example with 26 Bits the mask for the last Byte is: = = 3 Now let us mask the data received: CAh AND 03h = 02h So the WIEGAND data in this example is in fact: A8 DF D8 02 The BARIX X8 keeps this data in the registers 12 to 16 and will NOT read further WIEGAND data until register 11 is cleared (Reg. 11 = 00h). BARIX AG 14/24

20 Barix TS Temperature Sensors Barix offers a rubber encapsulated digital 1-wire temperature sensor (DS18B20) under the product name BARIX TS. Features: 12 bit resolution, 0.5 C accuracy from 10 C to +85 C, wide range: 55 C to +125 C ( 67 F to +257 F) The sensor cable has a green wire (GND) and green wire with a white strip (DQ). Up to 8 Barix Temp sensors can be attached to the BARIX X8 as shown in the schematic below: GND GND TS7 DQ DQ TS0 At Power-Up the BARIX X8 is scanning all 8 inputs (I/O0 I/O7) for attached TS sensors. Each found sensor is represented by the corresponding Bit in the High Byte of register 11, e.g.: - 2 Temp sensors attached to I/O0 and I/O b = 8100h The raw data of each Temp sensor (typically 12bit resolution, see Dallas datasheet) value is stored in the Modbus registers 3 to 10. Example code for calculation in degree Celsius: IF value < THEN temperature = value / 16.0 ELSE temperature = (value ) / 16.0 ENDIF Note: Divide by 2 (instead of 16) when using 9bit sensors! Examples: Reg 3 = 0181h, calculation: 385 /16 = C Reg 3 = FF5Eh, calculation: ( )/16 = C BARIX AG 15/24

21 Connecting to Barix Barionet100 device Power wiring The Barix Barionet100 is powered using pin 15 (Vcc) and pin 16 (Vss). In order to power the BARIX X8 connect two wires to the Barix Barionet100: connect Pin 15 (J6) to Pin 4 (J3) of the BARIX X8 (VIN) connect Pin 16 (J6) to Pin 5 (J3) of the BARIX X8 (VIN) Alternatively the X8 can be powered from Barionet s J4 or J5 connector (Pin1 & Pin2) also. Attention: do not use an AC power supply when connecting the BARIX X8 to Barionet! Use a DC power supply instead! RS-485 wiring Connecting the RS-485 bus is simple as the RS-485 signals are available on J7 which is also a detachable screw terminal block: Pin Reference GND 2 Not used 3 Not used 4 RS-485 A 5 RS-485 B 6 Reference GND Pin 4 (J7) to Pin 2 (J3) of the BARIX X8 (RS-485 A) Pin 5 (J7) to Pin 3 (J3) of the BARIX X8 (RS-485 B) When communication problems occur two measures can be taken to improve the RS-485 signal quality. Reference wire When using two separate power supplies a third wire should be used to ensure a common voltage level : Connect Pin 1 or Pin 6 (J7) to Pin 1 (J3) of the BARIX X8 RS-485 termination When the two devices need to be connected over a long distance both sides of the cable should be terminated using a 100 Ohm resistor to suppress signal reflections: Connect a 100 Ohm resistor between Pin 4 and Pin 5 (J7) directly at the terminals of the Barionet controller Connect a 100 Ohm resistor between Pin 2 and Pin 3 (J3) directly at the terminals of the BARIX X8 BARIX AG 16/24

22 Connecting to Barix Barionet50 device Wiring over Extension port The Barix Barionet50 has an extension connector (J10), this can be used to connect the Barix X8 module: Pin 1 (J10) to Pin 4 (J3) of the BARIX X8 (VIN) Pin 2 (J10) to Pin 5 (J3) of the BARIX X8 (VIN) Pin 3 (J10) to Pin 2 (J3) of the BARIX X8 (RS-485 A) Pin 4 (J10) to Pin 3 (J3) of the BARIX X8 (RS-485 B) Attention: do not use an AC power supply when connecting the BARIX X8 to Barionet! Use a DC power supply instead! Wiring over screw terminals Alternatively the Barix X8 module can be also connected to the Barionet50 s screw terminals. then connect the data cable (RS-485 bus) to Barionet connector J4: Pin Ground 2 +5V (max. 100mA) 3 Ground 4 RS-485 A 5 RS-485 B 6 Shield Pin 4 (J4) to Pin 2 (J3) of the BARIX X8 (RS-485 A) Pin 5 (J4) to Pin 3 (J3) of the BARIX X8 (RS-485 B) To power the X8 from Barionet50 s screw terminal connect the X8 to connector J2 : connect Pin 1 (J2) to Pin 5 (J3) of the BARIX X8 (VIN) connect Pin 2 (J2) to Pin 4 (J3) of the BARIX X8 (VIN) Reference wire When using separate power supplies for Barionet and X8 a third wire should be used to ensure a common voltage level: connect Pin 1 or Pin 3 (J4) to Pin 1 (J3) of the BARIX X8 RS-485 termination When the two devices need to be connected over a long distance both sides of the cable should be terminated. The Barionet50 has a hardware termination switch (S1), which enables a 100 Ohm termination when turned ON. BARIX AG 17/24

23 Modbus Register Map The BARIX X8 implements some registers in the Modbus address space. Access to unimplemented locations generates an exception. The Modbus address space is divided into multiple address maps, all registers in size. The BARIX X8 implements the coils (output bits) and the registers (16 bit). Reading back discrete (1bit) values is not supported. Attention: The device register addresses count from 1, while the Modbus protocol addresses start at 0. This documentation uses the device register number in the Modbus protocol the address must be one less!! Example: Device register 1 is addressed in Modbus/RTU as 0. Live I/O The state of the outputs can be set/reset using set coil and write register commands. In addition, the state of the outputs can be read back using the read register command. In the coil address map, only positions 1..8 (Modbus/RTU addresses 0..7) are populated in the BARIX X8, which are mapped to outputs Write access to any other address is prohibited. In the register address map, the outputs can be written simultaneously by accessing register 1. Bit 0 is output 1, bit 1 is output 2,... bit 7 is output 8. The state of the inputs 0 to 7 can be read using the read input register command on register 2 (see corresponding bits 0 to 7). The analog values (10bit res. [ ] / sampling rate 62.5 Hz) of each input can be read using the read input register command on register 3 (input 0) to 10 (input 7). When a Barix TS temperature sensor is connected the analog voltage is replaced by the temperature (for each attached sensor) in the same register! BARIX AG 18/24

24 Configuration Data All configurable parameters are accessible using standard Modbus read/write commands to registers. The configuration information area is 256 bytes, which is accessible as registers in the Modbus memory map. Of each configuration register only the lower 8 bits (Byte not Word) are used. The first 16 bytes of the configuration registers are onetime writable only after setting these registers to a value not equal to 255 (hex 0xff) they can not longer be changed. In the first 8 bytes, Device type, software version, and serial number are stored (ID registers). The remaining 8 bytes can be used by the installer to write permanent information (like shipping date, system ID, location etc). The next 16 bytes are used as configuration registers. The remaining registers ( ) can be used to store user information. ID registers Device information such as device ID, software version etc can be accessed using standard register read commands. This information is read-only and cannot be overwritten. The information is accessible using standard reads from addresses Register 257: set fixed to 0xB2 (stands for BARIX X8) Register 258: software version, 06 at the time of printing. Register 259: first part of the serial number (byte) Register 260: second part of the serial number (byte) Register are reserved for future use by Barix Register are usable as one-time writable storage by the installer or controlling software. BARIX AG 19/24

25 Configuration registers Device configuration can be set and read using standard Modbus commands. The BARIX X8 will reset its actual communications parameters to these values anytime it does not receive valid host communication for more than 5 seconds. Register 273: Pull up resistor yes/no (1=yes, 0=no) Register 274: Serial interface speed Bit 0 : 0 selects baud / 1 selects 9600 baud WIEGAND support Bit 6 : 0=disabled / 1=WIEGAND enabled Serial interface parity Bit 7 : 0=Even parity / 1= No parity. Register 275: Register 276: This register holds the Modbus address of the unit. I/O function setting (1=output, 0=input) Register : Reserved for future enhancements. Note, after changing configuration parameters it is recommended to restart / repower the Barix X8 module. BARIX AG 20/24
